 * The InputSetting class allows for getting a reference to either the global or local members.

 * using the SetValue() member function found in the Setting class. The primary purpose of this
 * class is to store an array of 10 PlayerInput structs for both the global and local (per-game)
 * setting and allows for easily accessing and modifying both settings.
